Specification of Letters Patent.

Patented Aug. 6, 1918.

To all wfiam-it-may concern:

Be'it: knownthat I, PETERPLAN HNGA, of Rochester, im the county ofMonroe and State at New York, haveinvyentedi contain mew and useful!Improvements in She/pens and the like; and! 1 do: hereby declare thefollowingeto be a fiull; clear, and enact description of the samercfienence: being; bad to the accompanying drawings; fiormin a punt GEEthisispecifinauion, and to the n orence' chair-acetone marked thereon.

My: inlvemion relates to impnovements in shapers and theulike' and has?for its object to provide more particularly means for readily adjustingthestnokeofi shape! rams on-tool slides of othermetal cutting. machines;so that; thee-path of travel at therein or slidmmay beshifted eithen'forwandly or hackwiardly asdesired according; to the nature of the workto be performed. A feather obj act of the invention: is to providemeansifor quickly and. positively locking the ram adjusting mechanism atwhatever points it isdesirod to hold the same. To these and other ends.the invention consists in certain improvements and combinations ofpants, all, as will: he heneinafiter more 11115 descnibed, the'novelfeatures being pointed out in theclhims at the end of the specification.

labels in threa chine upon which is carried an approved fommof worksupportsuch as that indicated at It for" holding the work piece 12which, int the present instance comprises a shaft upon which it isdesired to form a longitu- The: V- shaped rain 13 is slidably mountedupon suitable guides formed at the top of the ooluannas shown in F igs;1 and 3. The tool 14: iscarried on an adjustable head 15 at the forwardend of the rain. Mounted Within the ram isa slide block 16 to which: ispivotally connected at 17- the rocker arm 18, the lower end of whichslides in the socket formed in the shoe 19 whichhas a rocking motion on.a shaft passing through the column. llhc top of the rocker arm 18 issaconstruoted that the long shaft 12 forming. the won; piece may bepassed therethrough without intenfering with the operati-onflof the arm;

The driving mechanism for the ram comprises the pinion 20 meshing withthe gear 21 carrying the crank 22 and slide block 23 for! rocking thearm or slotted lever 18 whereby movement of the slide 16 is eiiected toreciprocate the ram 13.

The adjusting mechanism for the ram comprises thetransverse threadedblock 2+1 withwhich is connected the feed screw 25, the-front of thescrew having a journal 26 rotatable in a bearing 27 formed upon thebackof the slide block16 as shown in Fig. 1. The: slide block has arecess 28 formed at its center to receive the intermoshing beveled gears29 and 30, the former being rigidly connectedwith an extension 31 uponthe journal 26 and the latter rigidly connected with a vertical shaft;32, the lower end of w lziichv is preferably seated in a cavity formedinthe bottom wall of theslide block while theupper end extends through theslide block and ram to receive the operating handfle 33, which is keyed:or otherwise rigidly connected with said shaft.

Means for clamping the slide block upon the ramcomprises theslecveor'quill 34 and the lever 354501? rotating the same, @thesleeveextending through thetop wall of the slide ed engagement. therewith,while t-h e slideblock is provided-withguides 36-slidahly mounted uponthe guideways 37 termedupon the ram as shown in Fig. 3, it beingunderstood j that movement of the lever 35! in one? direction willtighten the slide 1 block upon the ram and movement of said lever in anopposite direction will loosen the same. The hand wheel 33 is rotatablymounted upon the top of the sleeve 34 so that rotation of said wheelwill not effect rotation of the sleeve. Accidental removal of the handwheel 33 from the sleeve is prevented by the reduced end of a set screw38 extending into a groove 39 formed exteriorly of the top of the sleeveas shown in Fig. 3. The sleeve also provided with a collar 40, the upperside of which forms a seat for the hand wheel and the lower side actingto prevent upward movement of the lever 35.

In order to provide a positive locking means for the slide block 16 Ihave rigidly connected preferably with the beveled gear 30 a gear wheel40, the teeth of which are adapted to normally receive the lockingprojection 41 on the bottom of the plunger head s 2 actuated by thespring 43 in the cavity 41 formed in the front wall of the slide block16. Rigidly connected with the lower extremity of the sleeve 34 is a cam4-5 positioned opposite the upper portion of the plunger head 42 andmovable by operation of the lever to actuate the plunger outwardly untilthe locking projection a1 disengages the teeth of the gear so that thehand wheel 33 and shaft 32 may be rotated to operate the feed screw 25for adjusting the ram 13.

The feed screw block 24 is provided at its upper side with a projection46 extending upwardly between and in sliding engagement with the guides47 formed upon the ram as shown in Fig. 2. The block 24 is connectedwith the upper wall of the ram by the machine screws 48, the heads ofwhich fit. loosely in the cavities 49 formed in the ram so that a slightup and down movement of the block is permitted. In order to preventrocking or shifting of the block by the action of the feed screw I haverigidly connected therewith a pin 50 which is snugly fitted in anaperture formed in the upper wall of the ram. the pin being free toslide up and down in the aperture while being prevented from movinglaterally therein. In the operation of the ram adjusting mechanismmovement of the ram either forwardly or hackwardly is effected byturning the hand wheel 33 to rotate the ment with the teeth of the gear40 as shown in Fig. 4. With the parts in this position the slide block16 is positively looked upon the ram and release of the block is madedependent upon movement of the lever by the operator. Operation of thelever to rotate the cam for the purpose of releasing the plunger 42 tolock the ear 40 will at the same time cause the ri s 36 of the slideblock 16 to be drawn into clamping on agement with the guides37 of theram as s lOWIl in Fig. 3. It will thus be seen that both the clampingand locking mechanisms for the slide block are simultaneously operatedby movement of the lever 35 and sleeve 34, the clamping of the slideblock upon the ram serving to provide a rigid connection for the rockerarm while the latter is in operation and the gear 40 and plungerprojection 41 a positive locking means to prevent acci-- dentaldisplacement of the operating sleeve 34 while the ram is beingreciprocated upon the frame or bed of the shaper.
